I am responding to a private message from venmic. I am happy to elaborate on this. :-)

Recent findings lend strong support to the theory that a black hole lies at the center of the Milky Way and of many of the 100 billion other galaxies estimated to exist in the universe.
(A) that a black hole lies at the center of the Milky Way and of
(B) that a black hole lies at the Milky Way’s center and
(C) that there is a black hole lying at the Milky Way’s center and
(D) of a black hole lying at the Milky Way’s center and
(E) of a black hole that lies at the center of the Milky Way and of


Rather that pick through each answer one at a time, let's attack this strategically, looking at splits. See this blog for more on this strategy:
http://magoosh.com/gmat/2012/gmat-sente ... trategies/

The first split is "that" vs. "of" at the very beginning. The phrase "a theory that A did B" is idiomatically correct. The phrase "a theory of A doing B" is inferior --- this construction will not be correct on the GMAT. Right away, (D) & (E) are out.

The phrase "a black hole lies ...." is active and direct, just what the GMAT likes --- we see this in (A) & (B). Meanwhile, (C) has the abominably indirect monstrosity "there is a black hole lying ...." On the GMAT SC, any time you have a choice of "[noun] [verb]" vs. "there is a [noun] [participle]", then every single time, the first will be correct and the second will be wrong. Here, we can eliminate (C) on these grounds.

Finally, we have the complex parallel construction at the end of the sentence:

....lies at the center
// of the Milky Way
and
// of many of the 100 billion other galaxies estimated to exist in the universe.


We need these to prepositions in parallel --- we are talking about something at the center of both the Milky Way and other galaxies. That means we must construct the first part in parallel ---- so "Milky Way's center" is wrong because it violates the parallelism. We need "of the Milky Way and of" at the end of the underlined section, to complete the parallelism correct. Only (A) & (E) do this correctly, but we have already eliminated (E) for other reasons.

This leaves (A) as the only possible answer.

Does this make sense?

Mike :-)

C. that there is a black hole lying at the Milky Way’s center an
D. of a black hole lying at the Milky Way’s center and

D & E out - Meaning changed

C out - passive voice

B can be elimiated cause the first part of the sentece that says 'that a black hole lies at the Milky Way’s center' is perfect but the second half ' Milky Way and of many of the 100 billion other galaxies' tends to change the meaning.

Lets simplify this -
A - black hole lies at the center of X and of Y
B - Black hole lies at the X's center and Y

A can be selected as a better bet.

Please post the OA.

(D) of a black hole lying at the Milky Way's center and

Set26-36

lets say phrase "A" is "the Milky way"
and phrase "B" is "many of the 100 billion other galaxies estimated to exist in the universe"

then the whole sentence takes the form:

Recent findings lend strong support to the theory that a black hole lies at the center of "A" and of "B".

which means" that a black whole exist at the center of "A" and at the center of "B"."

because we can omit the repeating words the sentence becomes:
"that a black hole exists at the center of "A" and of "B"."

Hence the answer is A.

Problem with B: Breaks parallelism; black hole lies AT the Milky Way's center and [those of] many of the 100 billion..
Also, as seen above, removing the parallelism issue will make the sentence sounding even more weird. The key issue is since we are saying AT THE MILKY WAY'S center ... then we must MIRROR the same structure in the second phrase as well.

Hi mates,

although the OA has already said, let me post my explanation

the key point is //ism: "the balck hole lies at the center of the --- and of ----"

The other possibility could be E, but this answer changes the meaning if the sentence

IMO A

Recent findings lend strong support to the theory that a
black hole lies at the center of the Milky Way and of
many
of the 100 billion other galaxies estimated to exist in the
universe.
A. that a black hole lies at the center of the Milky Way
and of --> most precise in meaning: a black hole lying at the center of milky way and at the center of many of 100 billions other galaxies, is estimated ... and that clause is correctly used to modify for the theory
B. that a black hole lies at the Milky Way’s center and -->not clear as (A) because black holes is not clearly stated where it is lying in 100 billions other galaxies
C. that there is a black hole lying at the Milky Way’s
center an --> there is is awkward and also, same error as (B)
D. of a black hole lying at the Milky Way’s center and --> of a is not precise as the use of that clause and same error as (B)
E. of a black hole that lies at the center of the Milky Way
and of --> same error as (D)

Milky Way is one of the galaxies I suppose (though not sure :-D)

So in my opinion author wants to say:

Recent findings lend strong support to the theory

that a black hole lies at the center of the Milky Way and

[same black hole lies at center]of many of the 100 billion other galaxies estimated to exist in the universe.

which can be written using option A. So thats why answer is A. But not a very good question :wink:

My take : Option A

D & E are out for the above mentioned reasons..

Usage of 'and' compels us to maintain d parallelism..

It is not only at the center of Milky Way but also at the center of other galaxies in d universe.. So 'center of' should be there and goes well with A..

Hope it helps..

Just a quick query Club members and Gurus ;
Let's say the Recent findings lend to two things
1) a black hole lies at the center of the Milky Way
2) many of the 100 billion other galaxies exist in the universe(I have modified the sentence , now we have a verb rather than verb-ed modifier )
In this case do we need to repeat the THAT in each part.
"theory that A and that B" or "theory that And B " which is correct.. [ both A,B are independent of each other]

Dear Sujit2k7
It's not a hard and fast rule, but typically "that" clauses are long enough that it makes sense to use two separate "that" clauses simply for rhetorical clarity. It's not grammatically wrong to say "I think that P and Q", but because P & Q are probably relatively long clauses, having a second "that" will just make the overall sentence structure much clearer. The GMAT absolutely will not test this particular point on the Sentence Correction.
BTW, if you're interested, here's a blog on talking about beliefs -----

I completely agree with the reasons on why options B, C, D, and E are incorrect. However, I am unable to understand the original sentence itself.

If the sentence were "Recent findings lend strong support to the theory that a black hole lies at the center of the Milky Way and of many of the 100 billion other galaxies.", I would have agreed that the parallelism is maintained (thought I would never understand how one black hole can lie at the center of the Milky Way and at the center of many of the 100 billion other galaxies at the same time :) -- each of the galaxies can have a separate black hole of its own -- presence of "a" before "black hole" has created an absurd theory!).

However, the original sentence structure is:
..... a BH lies at the center of the X and of Y estimated to exist in the universe.
What is "estimated to exist in the universe" -- answer is "100 billion other galaxies" which is a part of Y. Thus "the Milky Way" is not parallel to "many of the 100 billion other galaxies estimated to exist in the universe".

I am not able to find any sensible meaning of the sentence. Any help on this will be appreciated. I tried to find the source of the question, but could not find anywhere. I doubt whether this question is from any reputable source and worth brainstorming!

Dear doe007,

Consider the sentence ---
I would like to drive the car of my neighbor and the car of each one of his friends.
Admittedly, not a gem of rhetoric, but grammatically correct. Well, the underlined cars are in parallel, and in parallel, we are allowed to drop common elements, which omission would shorten the sentence to
I would like to drive the car of my neighbor and of each one of his friends.
This sentence, slightly better though still not ideal, is also grammatically correct. Notice, this sentence in no way implies that there is only one car, shared by neighbor & friends alike ---- rather, it quite clearly implies: my neighbor has one car, and each one of his friends has one car, and I want to drive all these cars (presumably not all at once).

Similarly, with the sentence:
Recent findings lend strong support to the theory that a black hole lies at the center of the Milky Way and of many of the 100 billion other galaxies.
A perfectly good, perfectly clear sentence, both grammatically and logically correct. Consider the expanded version -----
Recent findings lend strong support to the theory that a black hole lies at the center of the Milky Way and that a black hole lies at the center of many of the 100 billion other galaxies.
This version is far less economical, and therefore more awkward and clunky, but it makes more explicit the parallelism. This sentence says there is "a black hole" at the center of the Milky Way, and if we went to interview every other galaxy in the Universe (all 10^11 of them, admittedly, a large task!), then if we asked the spokesman of each galaxy, "Does your galaxy have a black hole at its center", the answer for the majority would be "Yes, we have a black hole at the center of our galaxy." The word "each" might have made this a shade more clear, but really it's perfectly clear from both versions above. The fact that "a black hole at the center" is a condition true for the majority of galaxies in now way implies that it is the same black hole. You are not reading the parallelism properly.

Does all this make sense?
Mike :-)

Recent findings lend strong support to the theory that a black hole lies at the center of the Milky Way and of many of the 100 billion other galaxies estimated to exist in the universe.

Sentence structure in (A):

Recent findings
lend strong support to the theory

that a black hole lies at the center
of the Milky Way and (parallel list 1)
of many of the 100 billion other galaxies estimated to exist in the universe. (parallel list 2)

Dear adkikani,

I'm happy to respond. :-)

In that sentence, the word "estimated" is a past participle acting as a noun modifier, and it modifies "other galaxies." You are correct.

Mike :-)

Agree with you that question is weird but B is def not correct.

B violates parallelism and gives entirely different meaning.

When I use B I get feeling that sentence is talking about 2 theories one about black hole and other abt galaxies.
